Types of Computer Languages: There are many types of computer languages, which can be categorized into the following four types:- a) Low-Level Languages b) High-Level Languages c) User-Friendly Languages d) Object-Oriented Languages
Computer Languages: a) Low-Level Language: Languages, which computer can understand directly and are machine dependent are called Low-Level Languages. For Example: Machine Language & Assembly Language.
Computer Languages: b) High-Level Language: The languages, which computer cannot understand directly and are not machine dependent are called High- Level Languages. Some are:- i. BASIC (Beginners All Purpose Symbolic Instruction Code) ii. C etc…
Computer Languages: c) User-Friendly Languages: These languages are very easy to codify and simplest to learn. Some are:- i. dBASE ii. Oracle iii. MS Access etc…
Computer Languages: d) Object-Oriented Languages: The languages which are based on object oriented programming (OOP) approach are called as Object-Oriented languages. For example:- i. Smalltalk ii. C++ iii. Object COBOL iv. JAVA v. Simula etc…
Language Translators: The software, which converts the codes of other languages into machine code are called Language Translator. Language Translators are categorized into three types:- 1) Assemblers 2) Interpreters 3) Compilers
Language Translators: 1) Assembler: Assembler translates the assembly language code (source program) into machine language code (object program). The Microsoft assembler program (MASM) & Borland Turbo assembler program (TASM) are two popular assemblers. Assemblers are used mainly in development of system software.
Language Translators: 2) Interpreters: Interpreters translate the high- level language code into machine language code, command by command. They are very slow for executing large programs, so interpreters are not suitable for most of applications development.
Language Translators: 3) Compilers: As contrast to interpreters, compilers provide faster execution speed. Compilers translate the entire program (source code) into machine code (object code). By using linker, the object code is converted into executable code. Compilers are widely used in translating codes of high level languages. As compared to assemblers or interpreters, compilers are preferred in development of application software.
